Quasiparticle tunnelling in two coupled chiral SYK model
Avik Chakraborty, Manavendra Mahato
The chiral SYK model is a 1+1 dimensional generalisation of the Sachdev-Ye-Kitaev model with chiral Majorana fermions and homogeneous random interactions. In the large-N limit, the…
Junctions, strings, clocks and gravitational memory in three dimensional dS space
Avik Chakraborty, Jewel Kumar Ghosh, MartÃn Molina +1
We show that non-trivial stringy excitations in Lorentzian three dimensional de Sitter spacetime can be created self-consistently from gravitational memory in the infinite past. In…
The degrees of freedom of multiway junctions in three dimensional gravity
Avik Chakraborty, Tanay Kibe, MartÃn Molina +2
We demonstrate that -way junctions in three dimensional gravity correspond to coupled strings each satisfying the Nambu-Goto equation in the smoothened background, and wit…
Decoding the string in terms of holographic quantum maps
Avik Chakraborty, Tanay Kibe, MartÃn Molina +2
It has recently been shown that the Nambu-Goto equation for a string emerges from the junction conditions in three-dimensional gravity. Holographically, gravitational junctions are…
Decoding multiway gravitational junctions in AdS in terms of holographic quantum maps
Avik Chakraborty, Tanay Kibe, MartÃn Molina +2
It has been shown that multiway junctions gluing copies of locally AdS spacetimes () can be described by strings obeying non-linear Nambu-Goto equations coup…
Renormalization of Einstein-Gauss-Bonnet AdS gravity
Giorgos Anastasiou, Ignacio J. Araya, Avik Chakraborty +2
The asymptotic analysis for the metric of a generic solution of Einstein-Gauss-Bonnet AdS theory is provided by solving the field equations in the Fefferman-Graham frame. Using sta…
